Director salary

Dear Sir / Madam,

1) what are the general payables to Directors from a Pvt Ltd Company, apart from their salary? If any other payments are made to them, do they attract Tds?

2) On what criteria, bank loans are based on? Whether by total income? or by taxability? More details about this?

3) What are the conditions for Director salary in view of Income tax?

4) Which ITR form should be used for this?

Early reply would be greatly appreciated.

Thanks / Maya.
